To point out damage like a bruise, epoxy system is used in the new technology
Inspired by the self-healing capabilities of animals and plants a new technology may make it possible for the plans to point out even the most diminutive holes to mechanics upon landing besides allowing the damaged planes to heal them while on the fly. If this technique becomes successful, in the future wind turbines, aircrafts and even spaceships may posses fixed circulatory systems with a thick synthetic paste that will enter into these holes and cracks and then under ultraviolet light it will incandesce to point out the damages like a bruise.
Plastic-based composites that are also known as fiber-reinforced polymers will be used as a particular help for the system. These polymers are getting quite popular among aircraft, wind-turbine and automotive manufacturers who use this material as protective layers of skin.
Ian Bond, an aerospace engineer at Bristol University in the United Kingdom, says in this connection “The weak point is that they are quite prone to damage that is mostly can’t be detected through the eye and the users of composites have to spend a lot of time in their efforts to detect this damage and they also get worry about the coming crucial times when the damage grows”.
Bond and his colleague started to balance the defect with biological systems inspired hollow glass fibers. The Engineering and physical Sciences Research Council is backing the research.
Black carbon fiber composites are not supportive to a color change and magnetic nanoparticles would be supplementary to the epoxy and because of newly formed epoxy plug a handheld magnet-based scanner may prove useful to detect changes in their virtual distribution.
Other scientists have moved to infrared camera that identifies the flaws below the surface, ultrasonic waves to monitor the expansion of flaws that become cracks and optical fiber sensors that counts defects and measures temperatures in the composite structure in real time.
